Abstract

A synchronization system comprising a memory device having a single row or clock register containing a series of first signals of a characteristic representing increments of time and at least one second signal of different characteristics representing the synchronism of a cycle of operation, means for detecting said clock signals, pulse generating means for producing synchronization pulses synchronized in said cycle to correspond to different predetermined multiples of said increments, means that respond to said first signals to produce synchronization signals for each increment of time through said operating cycle to control said pulse generating means and means responsive to the stopping of said second signal to provide a signal to check the operating accuracy of said generating means, of pulses once per operating cycle to (Machine-translation by Google Translate, not legally binding)
